In the midst of our very chaotic move we were able to get my car on the dyno and finally test this bad little boy. The results were very nice and we are really impressed with the turbo. The car is now making 75 more WHP at Redline on pump gas!

The First graph here is just the numbers. Here is what she did last night on the dyno. we are pretty impressed!

Now here is that same graph in STD Correction for those that are used to using the "Standard" Correction factor

And last but not least here is the HP curve outlined over the tune with the stock tubro. All that was changed was the FPGreen and the fuel modifications to support it. Look at the HP increase at redline!!!

All in all we are very happy with the results and considering the spool time we will deffinetely be recomending this turbo to our subaru customers.

Next on the modification path is to try this same combination with our AMS Top Mount Intercooler, Remove the Tumbers, Try an FP 3" Cover and toss an External Wastegate actuator on it. Oh, and of course throw some real gas at it

We think with some better boost control and a little less heat soak we can squeeze close to 400whp out of this little bolt on turbo.

Typical power range for this 2003 turbo is 360 to 380whp on pump gas. The only issue I see is that its comming on real late. THis turbo should be on by 3600 to 3800 full out. A retune of the AVCS system will help. Good job guys!

Clark

For some reason on the log it's showing full boost by 3850-3900 and i was ending the pulls just short of 7K. There might be some offset on the ignition pickup for some reason.

I tuned it last night in a hurry Clark and I tried only about 2 iterations of AVCS timing before we called it a night. Once Eric gets' his AP and we finish up our move I'll have some time to play with it.

Thanks! We'll be testing an 18g on our shop car next, I'm very curious to see how that does.

any plans to do a test on the 20g? that's what i'm leaning towards. also tell Chris to hurry and come back to the big island! my 04sti needs some more AMS love

Im sure that has something to do with it. I would of loved to pull out the tumblers and switch to our TMIC or even an AMS FMIC and test the stock turbo out again but time was not on our side with AMS being closed right now for our move.

Torque was a bit lower but the great thing about this car right now is that it pulls to redline like my evo did (only with much more power) and its making just about the same HP as torque. WAY higher then an EVO

Foo_Blyat, just an fyi if an evo were to make about 370whp on pump gas the torque number would be close to about 340 on this turbo, if not lower. The evo doesn't have a tumbler or a top mount to get in the way either. Food for thought.

I would love to get all of this done before the shootout but I just don't think we are going to have any time to do this. I looks as if the way the car sits right now is the way its going to see the shootout. We might toss some better gas in it and kick up the boost just because i'm power hungry and miss the strip

I don't see the point to keeping the stock tmic, seems like a huge restriction

Maybe this would answer some of your questions. Plus not everyone likes FMIC.

biggest problem during tuning was intake temps. i have ordered a turbo blanket as well as taken the stock snorkus intake and cut it right by the intake filter. helped out a little. i have yet to dyno the car but will hopefully get that done this week. i'll post my numbers up in this thread.
